BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an oxyhydrogen fuel producing device, and particularly to an oxyhydrogen fuel producing device with a plug-in electrobath, in which a direct current switching power supply is applied to the oxyhydrogen fuel producing device.

[0003] 2. Description of the Related Art

[0004] In a conventional oxyhydrogen fuel producing device, an electrobath is appled to electrolyze water contained therein for producing hydrogen and oxygen. Then, the hydrogen and oxygen are respectively delivered to a blowpipe by guide tubes. Thus, the blowpipe sprays the hydrogen and oxygen, forming a oxyhydrogen torch as an industrial cutting device or a heating device. In the aforementioned process, the water incompletely electrolyzed in the electrobath can be pumped out and transmitted through a heat dissipation device, such as a fan, for cooling down the water, so that the water can be recycled for further electrolysis. Thus, the conventional oxyhydrogen fuel producing device does not require a high-pressure steel cylinder.

[0005] In the aforementioned conventional oxyhydrogen fuel producing device, the electrobath is filled with electrolyte constituted mainly of water. Further, a plurality of electrode board are fixed inside the electrobath as the positive and negative electrodes, so that an electrode voltage dividing structure is formed in the electrobath. In this case, the oxyhydrogen fuel producing device produces hydrogen and oxygen by electrolyzing water in the electrobath as mentioned above.

[0006] However, the conventional oxyhydrogen fuel producing device and the electrobath has drawbacks as described in the following paragraph.

[0007] Conventionally, the electrobath in industrial utilization includes a high-voltage type and a low-voltage type. In the conventional oxyhydrogen fuel producing device, the preferred electrobath is the low-voltage type electrobath, which is generally operated in a voltage of 1.5V˜3V. Consequently, a transformer is required to transform the high voltage from the power supply to the operation voltage of 1.5V˜3V of the electrobath. However, it is well know that electromagnetic loss occurs in the voltage transformation of the transformer, which brings to a low power utilization rate of 50%˜60% only in the conventional electrobath. Further, the transformer has a relatively large size and heavy weight, which makes the conventional oxyhydrogen fuel producing device to be LARGE and cumbersome.

[0008] Further, the conventional electrobath has a structure in which a plurality of screws or rivets is utilized in assembly, and a plurality of insulation spacers are applied for necessary insulation. This increases the number of individual components of the electrobath, and increases difficulty in assembly or disassembly. Further, seals and O-rings are applied in the conventional electrobath to prevent electrolyte leakage. Generally, the seals and O-rings are made of rubber or plastic, which may decay or metamorphose in a certain period of time, so that the electrobath is not well sealed, and the electrolyte leakage may occur.

[0009] Further, the conventional electrobath has a single electrolyte inlet for filling. If a heat dissipation device or a cooling system is applied to recycle and cool the electrolyte, at least one heat dissipation inlet and outlet is required. However, the electrolyte in the electrobath may have a varied watermark in recycling and cooling, which is unfavorable in electrolyzing. Further, impurities may be produced in the electrolyzing process, and the impurities may build up in the electrobath and cause an unfavorable effect in electrolyzing.

SUMMARY OF THE INVENTION

[0011] Further, the present invention discloses an oxyhydrogen fuel producing device with a plug-in electrobath, in which the plug-in electrobath can be easily fabricated and constituted and has a preferred leakage-preventing performance. Further, the plug-in electrobath can be constituted to prevent the various watermark of the electrolyte in cooling and recycling and to reduce the built-up impurities.

[0012] The present invention discloses a plug-in electrobath of an oxyhydrogen fuel producing device.

[0013] In the plug-in electrobath of the oxyhydrogen fuel producing device, the heat dissipation inlets can be respectively provided on two sides of the casing, so that the electrolyte can be uniformly distributed in the casing. Further, the plug-in slot module can be formed with a long slot board or several short slot boards, so that the plug-in slot module can be versatile. Further, the casing can be made of insulating material, such as industrial plastic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0021] An embodiment of the oxyhydrogen fuel producing device 100 of the present invention is described hereinafter in detail with reference to FIG. 1. It should be noted that the structure of the embodiment is simplified, and only the components directly related to the present invention are denoted.

[0022] The oxyhydrogen fuel producing device 100 of the embodiment has a plug-in electrobath 105 as shown in FIG. 1. The plug-in electrobath 105 has electrolyte therein, and the electrolyte is drained out from a heat dissipation outlet 108 on the lower part of the electrobath 105 by a motor (a pump) 140 to a cooling tank 115 through path C. Then, the electrolyte passes heat dissipation fins 145 of the cooling system for cooling, and flows back to the electrobath 105 through path C for further electrolyzing. In the cooling system, a cooling fan 125 is used to assist the heat dissipation of the electrolyte by the heat dissipation fins 145.

[0023] Further, the oxyhydrogen fuel producing device 100 of the embodiment has a water replenishing system including an electrolyte storage tank 160 and an electrolyte replenishing tank 165. The water replenishing system is utilized to replenish the electrolyte when the electrolyte in the electrobath 105 is below a certain watermark. The electrolyte (mainly constituted of water) in the electrolyte replenishing tank 165 flows into the electrolyte storage tank 160 through path E, and the electrolyte in the electrolyte storage tank 160 flows into the electrobath 105 through path D. It should be mentioned that path D is a pipe connecting the electrolyte storage tank 166 and the electrobath 105 at the same height.

[0024] The electrolyzing process performed in the oxyhydrogen fuel producing device 100 of the embodiment is hereinafter described. The electrolyte (that is, the water) is electrolyzed in the electrobath 105 to produce hydrogen and oxygen. The hydrogen and oxygen are sent out from the gas outlet 106, and pass a filter tank 110 through path A. The filter tank 110 filters the hydrogen and oxygen, so that impurities and vapor mixed in the hydrogen and oxygen can be left in the filter tank 110. The vapor is then condensed in the filter tank 110 and recycled to the electrobath 105 for further electrolyzing. Then, the hydrogen and oxygen flow through path A to the cooling tank 115 and another filter tank 130 to further decrease impurity and humidity of the hydrogen and oxygen. Finally, the hydrogen and oxygen flow through path A to a blowpipe (not shown) for utilization.

[0025] It should be noted that only one cooling system is applied in the embodiment for cooling the electrolyte and the hydrogen and oxygen. In this case, the cooling system performs heat dissipation to both the electrolyte and the hydrogen and oxygen at the same time, which reduces the size and the weight of the oxyhydrogen fuel producing device 100. However, the oxyhydrogen fuel producing device 100 of the present invention is not limited to the embodiment; that is, two respective cooling system for the electrolyte and the hydrogen and oxygen can be constituted simultaneously in the oxyhydrogen fuel producing device 100 of the present invention.

[0026] Further, the electrobath 105 in FIG. 1 can be constituted to connect to a direct current switching power supply 200 as shown in FIG. 2, so that the DC switching power supply 200 supplies voltage required in electrolysis performed in the plug-in electrobath 105. The DC switching power supply 200 has a smaller size and a lighter weight, and supplies much more steady voltage than the conventional transformer, so that no transformer or rectifier is necessary in the present invention. Consequently, the oxyhydrogen fuel producing device 100 of the present invention is lighter and smaller.

[0027] Further, an embodiment of the plug-in electrobath 105 of the present invention is described hereinafter in detail with reference to FIG.1 and FIG. 2. The plug-in electrobath 105 has a casing 210, a plug-in slot module 220, and a plurality of electrode board 230 as shown in FIG. 2, and a gas outlet 106, a heat dissipation outlet 108, and a heat dissipation inlet 107 as shown in FIG. 1. The casing 210 and the plug-in slot module 220 can be made of insulating material, such as industrial plastic or other insulating matters. The insulating casing 210 is filled with the electrolyte, in which the electrolyte is mainly constituted of water. The plug-in slot module 220 is provided in the casing, and has a plurality of slots 250 with a fixed interval. The electrode boards 230 are respectively inserted in the slots 250 to form an electrode voltage dividing structure in the casing 210, so that the plug-in slot module 220 produces insulating between the electrode boards 230 without using conventional insulating spacers. The gas outlet 106 sends out the hydrogen and oxygen produced in electrolysis performed in the electrobath 105. The heat dissipation outlet 108 sends out the electrolyte in the casing 210 to the cooling system for cooling the electrolyte. The heat dissipation inlet 107 receives the cooled electrolyte to the casing 210.

[0028] It should be mentioned that, in the plug-in electrobath 105 of the present invention, it is preferred that the casing 210 has a slanted bottom surface, and the heat dissipation outlet 108 is provided on a lower position of the slanted bottom surface of the casing 210, such as the lower part of the plug-in electrobath 105 as shown in FIG. 1. Thus, the impurities can be easily built up on the lower position of the slanted bottom surface, and can be drained out through the heat dissipation outlet 108.

[0029] Further, it is preferred that the plug-in electrobath 105 of the present invention has at least two of the heat dissipation inlets 107 as shown in FIG. 1, and the heat dissipation inlets 107 are respectively provided on two sides of the casing 210. Thus, the electrolyte can be uniformly distributed in the casing 210, so that the electrolyzing is optimally performed.

[0030] Further, the plug-in slot module 220 can be formed with a long slot board 224 as shown in FIG. 3a, or can be formed with several short slot boards 222 as shown in FIG. 3b, so that the plug-in slot module 220 can be constituted with versatility.

[0031] The plug-in electrobath 105 of the present invention is assembled with the electrode boards 230 inserted into the slot 250, so that no screw or rivet is necessary. Thus, it is possible to reduce the number of rubber seals or O-rings applied in the plug-in electrobath 105; that is, the components of the present invention are fewer than the components used in the conventional electrobath, and the plug-in electrobath of the present invention has a preferred structure to prevent electrolyte leakage.

[0032] While the present invention has been described with reference to the preferred embodiments thereof, it is to be understood that the invention is not limited to the described embodiments or constructions. On the contrary, the invention is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art.
